killed database.yml, can i replace it?

Whilst trying to fix a problem with greyhole.yml, I aciddentally overwrote database.yml. So I restored it using

https://github.com/amahi/platform/blob/master/config/database.yml

Today, I have the

Ruby on Rails application could not be started

error message.

Code: Select all

Error message: Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (no such file to load -- active_record/connection_adapters/mysql2_adapter)

.

It can only be related to the mucked up database.yml because there is plenty of space on the hard drives. Are there any backups of this file?

Lessons learnt, maybe I should get crashplan to back up all these config files.

You could try reinstalling Greyhole. There should be guidance in the wiki on how to update. Same procedure would act as a reinstall.

Tried that, but it did nothing. So I setup a clone server on very similar hardware. Same Amahi version, based on Fedora 14. Then copied the database.yml from the new system, onto the old system, and it worked great.

The reason for setting up the cloned system, is so I can load the greyhole storage up with files, and do a dummy run upgrade to Ubuntu 12. I can test the performance before and after without muching up the real server, and at least it's working now.
